WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 759,603, dated IrIay 10, 1904.

Original application filed January 22, 14902, Serial No. 90,742. Divided and this application filed July 11, 1902. Serial No. 115,189. (No model-l To c/ZZ whom t may con/cera:

Be it known that I, J osnru FOSTER, a citizen of the United States, and a resident oit' New York city, in the borough ot' Brooklyn, county of Kings, and State oi' New York, have invented certain new and usei'ul Improvements in Water-Heaters, ot' which the following' is a specilication, taken in connection with the accompanying drawings, forming part of the same.

This invention relates to water-heaters which are especially adapted Yfor heating water lfor bathing and other similar purposes; and it relates especially to interlocking valves for use in such heaters.

This application is a division and continuation oi' my copending application, Serial No. 90,742, liled January 22, 1902, which has subsequently matured into Patent No. 705,335, of July 22, 1902.

In the accompany in g drawin gs,in which the same reference character refers to similar parts in the several ligures, Figure 1 is a partial sectional view ot a water-heater embodying this invention. Fig. 2 is a side View olli Fig. 3 a View showing a diilerent form o'f valve mechanism. Fig. 4 is a side view of the same.

The form of heater illustrated in Figs. 1 and 2 oi' the drawings comprises a mixing-chamber A, an injector B, having its heating-noz- Vrle B5 in line with the inlet of the mixingchamber, and interlocking valves for the admission oi fluids to the injector in varying proportions. The mixing-chamber A, which is secured to the wall or any desired support by the bracket A', comprises the curved deflecting-plate AL opposite the inlet A3 of the mixingchamber and extending substantially parallel to the circular wall of the mixingchamber. The two guiding-plates A5 extend outward from the wall of the mixingchamber, preierabl y on either side of the outlet A8, and have the curved formation indicated, so that they project within the deilecting-plate AJ. ln this way it will be evident that heated fiuids entering the mixing-chamber and impinging upon the deflecting-plate are divided and are by means of the. guidingplates made to impinge on the inner side of the deiiecting-plate and are thoroughly mixed before issuing' from the outlet A, cddies being formed in the spaces A A7 within the miXing-chamber. The mixing-chamber is rigidly secured to the injector Bby the screwed extension Aiot' the chamber, which lits within the upper end B of the injector-casing. As is indicated, the injectoris provided with the curved passage B2, through which water is supplied from the water-pipe E. The heating-nozzle B5 is located within the straight passage B and substantially in line with the inlet of the mixing-chamber, so that when steam is used in the heating-nozzle the force ot the steam-jet assists in discliarging the fluids from the injector and produces a greater pressure in the discharge than would otherwise be the case.4 The curved portion of the injector is formed with the drain-aperture B", which connects with a suitable drain-pipe B7. By this means any water which may remain in the injector, mixing-chamber, and adjacent parts is drained oil after the heater has been used, and the pipes are kept :tree in this manner. The valves which are used in this case for governing the admission of fluids to the injector are provided with interlocking handles, so `that it is necessary to open the water-valve before the heating-valve can be operated. Thereafter the heating-valve may be opened to any desired extent to admit any amount of the heating' fluid to the injector and to properly regulate the temperature oi' the water. In closing the valves it is necessary to entirely close the heating-valve before the water-valve can be operated. This is effected by the interlocking members on the handles secured to the valves. The heating-valve, which is secured, as is indicated in Fig. 2, to the heating-pipe D, is provided with the seat DS, with which the valve-plug D7 ot standard construction cooperates in a well-known manner. This valve-plug is mounted in the ordinary way on the valve-stem E and is positively moved by the same toward and away from its seat. Upon the stem is also rigidly secured the heating -handle D2, which may, if desired, be formed with the extension 'D and with the grip D3 :for more readily ope ating the same.

The heating-handle is provided with the adjustable stop D4, secured firmly to the handle by the screws or bolts D5, so as to properly coact with the water-handle. The seat and valve-plug of the water-valve are similarly constructed, and the valve-plug in this instance is also mounted on the valve-stein E. The water-handle is firmly secured to this valve-stem and is in like manner preferably provided with the extension E and with the grip E3. This water-handle is also preferably formed with the projection As will be seen in Fig. l, the water-handle is formed on its under surface with the interlocking member or cam E4, which projects into the path of the stop D4 on the heating-handle. The two valve-stems are preferably maintained at all times in proper alinement by the yoke E7, which embraces both of the valves, as indicated in Fig. 2, and holds them rigidly in alinement. These adjustable interlocking members operate as follows in regulating` the admission of fluids to the injector: In the position indicated in Fig. l both valves are completely closed, and it will be seen that the stop D4 engages the cam E4, so that the movement of the heating-handle in a left-handed direction, so as to open the heating-valve, is prevented. The water-handle may, however, be rotated in a left-handed direction, so as to admit water to the injector, and in operating the heater this water-handle is rotated until the projection E" comes into contact with the nut upon the end of the valve-stem D or with a contiguous part. In this position it will be seen that the cam E'i has moved out of contact with the stop D", so that the heating-handle is free to move in a left-handed direction, and the heating-valve may thereupon be opened to any desired extent to properly regulate the temperature of the water. The extension D8 operates to limit the movement of the heating-handle, since this extension comes into contact with the valve-stem E. In closing the valves the heating-valve is first moved back into the closed position indicated in Fig. 1, so that the stop B* moves out of the path of the cam El. Thereafter the water-handle is moved into the closed position indicated. As the valve wears to some extent during the normal operation of this device, it is desirable from time to time to adjust the position of the stop D4 so that it operates to insure the complete closure of the heating-valve. This is effected by releasing' the adjusting-screws D5 and setting the stop in any desired position and securing itin that position by tightening the screws, these screws passing through suitable slots in the stop. This arrangement has proved very effective in practice, and, furthermore, allows the employment of the standard form of valve, which is mounted directly on the valve-stem and while positively actuated thereby at the same time entirely prevents the opening of the heating-valve before the water-valve has been opened to the proper extent, so that unduly hot water cannot be delivered from the heater.

In the form of interlocking valve shown in Figs. 3 and 4 the structure of valve-seat and plug are the same as has been described, the plugs being secured in each instance to the valve-stems D and E', so as to control the admission of water and heating fluid from the pipes D and E to the injector. The heating-handle Gr is rigidly secured upon the valvestem D and is formed with the slot G and with an interlocking member or flange around its periphery. The yoke H is rigidly secured t'o the pipes and is provided with the stop-pin H', which projects through the slot G', and thereby limits the movement of the heating-valve. The water-handle F is adjustably secured upon the valve-stem E by the nuts F2 F3 or by any other desired means, so that it may be adjusted longitudinally of this stem. This handle is provided with an interlocking member or iiange around its periphery and with the slot F, through which the stop-pin H also passes and which operates to limit the movement of this valve. As is seen in Fig. 4, the interlocking members of these handles F and G come into close contact, so that in the position indicated when both valves are closed a movement of the handle G in a left-handed direction, so as to open the heating-valve, is prevented until the water -handle F has been turned. The movement of the valves in either case is limited to substantially half a revolution, which is suficient with the quick-acting valves used to secure the desired valve opening. In closing the Valve it is apparent that the heatinghandle G must be turned into the position indicated in Fig. 3, when the heating-valve is completely closed before the water-handle F can be turned into its closed position. The adjustability of the water-handle F upon the stem F/ serves to allow for any wear that may occur and secures the complete closure of the heating-valve under all conditions. If desired, the heating-handle and water-handle may in this instance be formed with eXtensions and grips similar to those that are indicated in Fig. l, although this is not necessary inevery instance.

Many modifications may be made in this device without departing from the spirit of this invention. Any desired form of valve may be used, and it is not necessary to employ the exact form which has been disclosed. Furthermore, parts of this invention may be used without employing all of the same. I do not, therefore, wish to be limited to the disclosure which has been made in this case;

but
